9.1 Software Check
Information about the device may be obtained from the About option
in the Configuration Menu. This information may be used when inquiries
are made to Micro Direct or a service agent.
9.2 Product Useful Life Checks
To ascertain whether the device has exceeded its useful life, Micro Direct
recommends checking the flowhead and the real time clock.
The flowhead may be checked with the daily calibration verification, to be
completed by the clinician/healthcare professional and during the periodic
inspection of the device. Reference section 5.4. Calibration Verification
for details on how to check the device flowhead.
The clock will reset if the 3V coin cell battery has depleted. This will be
evident as the Time-Date option will be displayed every time the device is
turned on until the battery is replaced and the time/date is set again.
The coin cell has an expected battery life of 15 years+ which exceeds the
devices product life; therefore, a service is recommended at 10 years or
when product useful life checks dictate it is required.
